.
To satisfactorily supply a large volume of air into big open
spaces such as shopping malls, leisure arenas and
gymnasiums, requires a certain type of diffuser. This type
of application is where the design features inherent in the
Model DRL are best demonstrated.
With adjustable vertical vanes located in a rotational
cylinder drum, the diffuser is capable of supplying
controlled ventilation over a long throw in both heating
and cooling modes. Whist normally used for horizontal
distribution, the diffuser may also be used for vertical
projection if required.
The diffuser is constructed from aluminium extrusions
and incorporates a flanged frame for easy installation. A
polypropylene bristle is used to seal the cylinder drum
inside for outer flange frame. With the diffuser in-situ the
cylinder is able to rotate a full 360 degrees, to allow
cleaning with or without an OBD fitted.
A complete range of eight standard sizes and four non
standard sizes comprises of seven small formats (type’S’)
and five large formats (type ‘L’). See page 10 for complete
dimension details.
Standard finish is silver (RAL 9006) or white ( RAL 9010)
stove enamel. Alternative paint finishes to the relevant
RAL colours are available on request.
Opposed blade dampers can be factory fitted and are
located to the rear of the cylinder drum. If required a
separate for fitting blade damper into the ductwork
behind the diffuser assembly.
Motorised Operation
To satisfy the demand for remote automatic operation, a
motorised version of the Model DRL is also available. The
cylinder drum is motorised to alter the air discharge angle
for heating or cooling modes. Cylinder travel can be
altered to suit on site requirements, by adjustment of the
motor. Internal air pattern vanes are manually adjusted
to the required position.
A 230 Volt A.C. or 24 Volt D.C. on/off motor can be fitted to
a built-in mounting plate assembly incorporated into the
standard diffuser.
The built-in motor mounting assembly is suitable for 275
high diffuser sizes only.
Manual Operation ( Model : DRL )
Motorised Operation (Model : DRL-M)
o
Example : from performance table, required throw 15m and air vol 610 L/S, using S4 diffuser @ 11 C gives 2.2m drop/rise,
o o
air will need directing up (cooling) 9 C or down (heating) 9 C (figs by interpolation).
Example : a 5 degree change of
blade angle causes a 10% decrease
in throw.
Discharge Correction
Continuation
Supply air temperature will
affect the row and air jet will
need correction achieve table
throw figures.
